encrypted ZFS Pool not importing after update 9.3

[seibax]

Hi,

i've made a clean fresh install 9.3 on USB stick. I reimported my old database, and when i want to unlock my encrypted ZFS pool, there is error:
Error: Volume could not be imported: 3 devices failed to decrypt (pool is 3 HDD).

Any idea?

I have NO backup of my encryption key, i thought passphrase is enough to unlock it again.... any hope?

sorry for bothering, found my key (luckily)....

btw: is it possible to import only with passphrase?

I had this same issue. I had to boot the old version and get the key. Then boot the new version and upload the key. I never knew I ever encrypted it.

If you do not have the key, I am pretty sure the data cannot be accessed. Ever.

Yeah I thought I was fooked. But obtaining it from the older version was cake.
